The Opportunity

The Senior Site Manager is the senior on-site leader responsible for directing and coordinating field installation execution for Thermo Systems projects. Partnering closely with the assigned Project Manager, the Senior Site Manager drives safe, high-quality installation outcomes, protects schedule performance, and ensures disciplined site coordination—surfacing issues early, driving resolution paths, and maintaining strong field controls.

This role serves as Thermo Systems’ site interface with customer representatives, general contractors, and third-party trades (including electrical subcontractors). In addition to execution leadership, the Senior Site Manager is expected to handle higher-complexity sites, lead more challenging stakeholder environments, mentor other site leaders, and elevate field practices that reduce rework and improve predictability across Thermo Systems’ installed base.

What You’ll Do

Core Responsibilities:

On-Site Installation Leadership (Safety, Quality, Execution)

• Own day-to-day on-site leadership for installation activities, ensuring work is executed safely, efficiently, and in alignment with Thermo Systems standards and customer requirements.
• Promote a safety-first culture: reinforce safe work practices, ensure compliance with site safety plans, and escalate unsafe conditions immediately.
• Lead field quality practices: verify installation workmanship, ensure inspections are completed, and coordinate punch list creation and closure.
• Serve as the senior on-site escalation point for field execution issues, driving rapid root-cause identification and corrective actions.
• Anticipate execution risks earlier and implement preventive controls (sequence discipline, workface readiness, quality holds) to reduce rework and schedule disruption.

Schedule Monitoring & Daily Coordination:

• Track installation progress against the approved schedule and short-interval plans; identify risks to milestones and drive corrective actions.
• Coordinate daily/weekly field meetings (toolbox talks, trade coordination meetings, look-ahead planning) as required by the site.
• Maintain clear visibility of site constraints (access, permits, shutdown windows, staging areas, material availability) and communicate impacts proactively to the Project Manager.
• Lead site-level recovery planning when slippage occurs (sequence changes, crew plan adjustments, constraint removal) and communicate options, risks, and require
